316 Stainless Steel Slip on Flange is not only saves space, reduces weight, more important is to ensure that the joint parts will not leak, with good sealing performance. The compact flange size is reduced by reducing the diameter of the seal, which will reduce the cross section of the sealing surface. Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing face matches the sealing surface. In this way, very little pressure is needed to compact the cover. With the reduction of the required pressure, the size and number of bolts can be reduced accordingly, so a new product has been designed that is small in size and light in weight (70% ~ 80% less than the weight of the traditional flange). Therefore, flat welding flange type is a better flange product, reduce the quality and space, for industrial use plays an important role.

Longquan is a large-scale 316 stainless steel blind flanges manufacturer and supplier in China. We have been specialized in stainless steel flanges, duplex steel flanges, super duplex steel flange, pipe fitting for many years. 316 stainless steel blind flanges has a good price advantage and cover most of the European and American markets.

Duplex steel S31803 threaded flanges is a kind of flange connected with the pipe by the thread. Design, according to the loose flange treatment. The advantage is that there is no need to weld, flange deformation on the cylinder or pipe generated additional torque is small. The disadvantage is that the flange thickness is large and the cost is high. Suitable for high pressure pipeline connection.

The 316 Stainless Steel Weld Neck Flanges is attached to the pipe end. It is the part that connects the pipe to the pipe. There are holes on the flange, and bolts can be worn to make the two flanges tightly connected, and the flange is sealed with a liner. Flanged pipe fittings are pipe fittings with flanges (flanges or joints). It can be cast, threaded or welded. The flange connection is composed of a pair of flanges, a gasket and a number of bolts and nuts. The gasket is placed between the sealing surface of the two flanges. After tightening the nut, the specific pressure on the surface of the gasket will be deformed after reaching a certain value, and the uneven part of the sealing surface will be filled to make the connection tight without leakage. A flange connection is a detachable connection. According to the connected parts can be divided into container flange and pipe flange. According to the structure type, there are integral flange, looper flange and threaded flange. Common integral flanges are flat welding flange and butt welding flange.
